FORECAST IN DETAIL

Did you enjoy yesterday's mid-80s? Might that have been the last 80-degree day of 2009? Hard to say. But it's easy to say that daily highs will mostly stick in the 60s for the next 5 days as a much cooler pattern establishes itself over the region. But for the few lingering showers this morning, the pattern will also be pretty dry -- at least through the middle of next week.

Today (Saturday): Behind the cold front that charged through the region overnight, cooler air will steadily stream into the region. Today's high temperatures will probably end up being at midnight last night, as temperatures remain steady in the upper 60s to around 70 during the day. A few morning showers are possible (40-50%), especially south and east of town (60% chance), before some partial clearing in the afternoon. It will become breezy with winds from the north at 10-20 mph. Confidence: Medium

Tonight: Partly cloudy and cool overnight as high pressure begins to build over the region. Lows will range from the mid-40s in the cooler suburbs to near 50 downtown. A light breeze from the north will blow at around 10 mph. Confidence: Medium-High

Keep reading for the forecast for tomorrow and into early next week...

Tomorrow (Sunday): Get out and enjoy what should become a picturesque, crisp fall day. Scattered morning cloud cover should decrease as the day wears on, and it will feel nice and comfy in the afternoon sun as temperatures reach the mid-to-high 60s. We'll have a light breeze from the west at 5-15 mph. Confidence: Medium-High

Tomorrow Night: It will probably be the coolest night of the fall thus far. Under clear skies and light winds, temperatures will drop all the way down into the upper 30s in the outer suburbs with mid-to-upper 40s downtown. Confidence: Medium-High

A LOOK AHEAD

Expect beautiful, autumn weather for Columbus Day. After the cold morning start, temperatures will rise to the low-to-mid 60s under sunny skies. Confidence: Medium-High

A weak frontal system will pass through the area Monday night and Tuesday. A few showers are possible (30% chance) late Monday night as temperatures drop down between 45 and 50. On Tuesday, it will likely become partly sunny and breezy, with brisk highs in the mid-60s. Confidence: Medium

At the risk of making some percentage of you immensely jealous and the other percentage grateful, at this moment it is 16 degrees in Boulder, Colorado, with a wind chill of 7 degrees and ~ 2" of snow on the ground.

For those keeping track, we've (here in central Colorado) shattered record low temperatures from 50+ years ago by 5-8 degrees, meaning that -- realistically -- this is easily the coldest weather at this time of year in > 100 years

...just a quick update from the West; thanks for listening...and -- snow lovers -- not being overly-jealous

NWS predicted a low of 62 this morning; it never dropped below 71. Major model bust!

Thanks for the report from Boulder. My husband is from Colorado and went to CU Boulder. He is always talking about how great the weather is in Colorado. I am ready for cooler temps here!

Speaking of snow in Boulder, today is the 30th anniversary of a record early snowfall for the Washington, D.C. area. On the morning of October 10, 1979, many areas around DC received 1 to 3" of snow with temperatures near freezing. National recorded .3". So, it can even happen around here, on rare occasions.

I remember that 1979 snowfall. I was driving to work in Alexandria well before 7 am and was completely shocked to drive in the snow. It was all melted by the time I stuck my head outside again (I didn't sit anywhere near a window) some time after 9 or 10 am.

1979 snowfall probably won't happen again this early due to global warming.

Cooling down here. Outlook is for possible frost well outside Beltway around midweek and a late-week storm with some rain possible. Not much more than sprinkles around here this morning.

1 1/4 inches of snow in Big Lake, Minnesota this morning. My buddy had planned to grill today, oh well.

Game Three of Phillies-Rockies ppd.

Will play it on Sunday at 8 pm their time.

Am I the only one thinking MLB should have the game played in the day, where it will be at least somewhat warmer than night?

Ratings and NFL are the factors but come on!

Yesterday was quite nice and we were able to take a nice walk on the Warrenton Branch Greenway.

Today's hi-temp at our location last night 64.0F. Currently down to 47.1F
